FreeSpace E4 Series II

Business Music System

1.STANDBY – The STANDBY button switches the unit between standby and active. The color of the LED above the switch indicates the status:

Amber = Unit is in standby Unlit = Unit is active

2.USB – A USB communications port (for future use)

3.SYSTEM STATUS – The SYSTEM STATUS LED indicates the condition of the unit.

Green = Normal Operation Red = Fault condition

4.AMP Outputs – These LEDs work in pairs (1 and 2, 3 and 4) and indicate the operating status of the four amplifier output channels.

5.AUDIO SOURCES – These LEDs indicate the operating status of the four input sources:

Green = Good signal Amber = Low signal

Red = Input signal clipping

6.DIRECT INPUT – The color of this LED indicates the condition of the source connected to the DIRECT IN/CONTROL connector on the rear panel. Amber = Active bypass

Unlit = Normal operation

The following accessories are shipped with the E4 unit in the FreeSpace E4 System Accessory Kit (PC030105).

• 2-terminal input connectors (6) – For wiring sensing microphones

• 3-terminal input connectors (2) – For wiring equipment to the MIC/LINE 3 input

• 4-terminal input connectors (3) – For wiring equipment to the AUX/OUT CONTROL, MIC/PAGE/LINE 4, and DIRECT IN/CONTROL inputs

• 2-terminal output connectors (5) – For wiring speaker cables to the AMP OUT connections

• Rubber feet (4) – For installing the E4 unit on a level surface

• Replacement voltage label (2) – Used on OUTPUT VOLTAGE selection switch

• FreeSpace system Installer™ software CD

Note: Please see sections 3.0 and 4.0 of the FreeSpace E4 Business Music System Owner’s Guide for unit placement guidelines, rack-mounting instructions, detailed connection information, and troubleshooting information.
